Game 10367791 please.....Is there a way to see who had the best % of BR games played to games won?

I won 2/8, and my bro(Soldier4Christ) won 2/5. 40%, thats pretty good.....I mean, well, anyone can play 50 and win 5, I was wondering who the best was %-wise - If you can't figure it out, or it's too much work its cool haha
